Abstract
Aim: Dietary supplementation with inorganic nitrate (NO3‒) may enhance exercise performance by improving skeletal muscle contractility and metabolism. CrossFit also, is recognized as a new method improves exercise performance but the interaction effects of nitrate supplements and CrossFitt on exercise performance are not well known. The present study was done to examine the interaction effects CrossFit training and beetroot juice on exercise performances in middle age inactive men.

Methods: In this quasi study, twenty inactive men (aged 21-30 years old), were randomly divided into beetroot juice + CrossFitt group (n = 10) or placebo + CrossFitt group (n = 10). All participants were performed CrossFit training 3 days a week for 8 weeks. At the end week of the intervention, supplement group received 140 mL beetroot juice containing about 800 mg of NO3‒ per day. Exercise performances were evaluated before and after the intervention.

Results: The results demonstrated that sprint, anaerobic power and vertical jump test were improved in the both groups (P<0.05), however no significant differences were observed between two groups. Peak aerobic power was increased in the both groups (P<0.05), while the increase of peak aerobic power was higher in the supplement group compare to the placebo group (P<0.05).

Conclusion: Generally, we can conclude that CrossFit training caused improves exercise performance but the interaction of beetroot juice and CrossFit cannot enhance these performances.
